Question

A certian machine makes electrical resistors having a meanresistance of 40 and a standard deviation of 2. Find the probability that a random sample of 36 ofthese resistors will have a combined resistance of more than 1458. Any help would be greatly appreciated! Thank you foranything! :) A certian machine makes electrical resistors having a meanresistance of 40 and a standard deviation of 2.

Explanation / Answer

if combined resistance is 1458, that means average is 1458/36 =40.5 z = (40.5-40)/(2/(36)) = 1.5 P(z>1.5) = 1-0.9332 = 0.0668
